OBJECTIVE
Inflammation plays a critical role in secondary brain damage after intracerebral hemorrhage (ICH). However, the mechanisms of inflammatory injury following ICH are still unclear, particularly the involvement of NLRP3 inflammasome, which are crucial to sterile inflammatory responses. In
Oxidative stress and persistent inflammation play crucial role in the progression of diabetic wound complications. Hemeoxgenase-1 (HO-1) by degrading hemin has been shown to display anti-oxidant and anti-inflammatory effects. Further, hemin is a potent HO-1 inducer. Thus, the current study was aimed
Tumor necrosis factor alpha (TNF-alpha) has multiple effects on iron homeostasis and erythropoiesis and has been implicated in the pathogenesis of the anemia of inflammation. We postulated that intracellular iron in turn may regulate the expression of TNF-alpha. In the human monocytic leukemia cell
The pathomechanisms of complications due to blood transfusion are not fully understood. Elevated levels of heme derived from stored RBCs are thought to be associated with transfusion reactions, especially inflammatory responses. Recently, the proinflammatory effect of heme has been Adipose macrophages with the anti-inflammatory M2 phenotype protect against obesity-induced inflammation and insulin resistance. Heme oxygenase-1 (HO-1), which elicits antioxidant and anti-inflammatory activity, modulates macrophage phenotypes and thus is implicated in various inflammatory diseases.
OBJECTIVE
Visceral adiposity and impaired glucose metabolism are common patho-physiological features in patients co-morbid with obesity and type-2 diabetes. We investigated the effects of the heme-oxygenase (HO) inducer hemin and the HO blocker stannous-mesoporphyrin (SnMP) on glucose metabolism,
Microvascular failure is a major determinant for the development of hepatocellular dysfunction after hemorrhagic shock. Induction of heme oxygenase (HO) 1 may confer hepatocellular protection. Hemin arginate (HAR) induces HO-1 and protects against shock-induced organ failure. The mechanisms are not
Intracerebral hemorrhage (ICH) is the most severe form of stroke and is further exacerbated by the secondary injury involving inflammatory response due to the activation of microglia. This secondary injury is partly due to the toxic effects of hemin, an endogenous breakdown product of hemoglobin.
Reactive oxygen species (ROS) from both endogenous and exogenous sources can cause oxidative DNA damage and dysregulated cell signaling, which are involved in the multistage process of carcinogenesis such as tumor initiation, promotion and progression. A number of structurally different

Hemin is a heme-oxygenase inducer, which can confer anti-inflammatory, cytoprotective, and antiapoptotic effects. These properties are beneficial therapeutical effects to inflammatory bowel disease (IBD). IBD is a worldwide health problem characterized by chronic inflammation of
OBJECTIVE
Although, pharmacological activation of heme oxygenase (HO)-1 has shown to produce ameliorative effects in various experimental models of inflammation, but such beneficial effects have not been observed in adjuvant-induced arthritis. Further, the upregulated activity of HO-1 has been
Alveolar macrophages (AMs) can initiate lung inflammation by producing pro-inflammatory cytokines and chemokines, but they participate actively in the prevention of inflammation during acute lung injury (ALI). Heme oxygenase-1 (HO-1) is mainly expressed in AMs and has anti-inflammatory properties in
Inflammation or vascular occlusion by parasitized red blood cell contributes to the pathogenesis of cerebral malaria. The current study aimed to characterize the role of major pro-oxidant factor methemoglobin present in the malaria culture supernatant contributing in inflammation during malaria.
Hemoglobin, hemin, and ferric ion (Fe) were shown to reverse peritoneal exudate cell (PEC)-mediated suppression of concanavalin A-elicited murine spleen cell activation. Titration of hemoglobin and hemin relative to Fe showed a direct relationship between Fe content and reversal of PEC suppression.
OBJECTIVE
To investigate the effect of hemin on lung injury following severe acute pancreatitis (SAP) in rats and to explore its rudimentary mechanism.
METHODS
Thirty-six rats were randomly divided into 3 groups: a control group, a SAP model group, and a hemin-pretreated group. Rats were sacrificed
